C93700 has excellent machining properties, medium
strength and good corrosion resistance and will withstand mild
acids as found in mine water.

Bearings manufactured from C93700 have excellent
wear resistance under conditions of high speed, heavy pressure
and vibration, have low friction and can be used where lubrication
is less than adequate and there may be minor misalignment. C93700
bearings require a hardened shaft and maximum shaft surface speeds
of 4 m/sec can be tolerated.

and depend on specimen size and orientation.

*Since brazing is performed at temperatures
within the hot-short range, strain must be avoided during the
brazing and cooling of this alloy.
